Monitoring a Fritz!Box using RRDtool

RRDtool is a popular and versatile program to store and aggregate time-dependent data in way that the size needed for storage is not growing indefinitely. Furthermore it has a powerful plotting engine to generate nice graphs. It is therefore widely used to monitor network devices.

The popular Fritz!Box router can be queried using the TR-064 protocol for the number of transferred bytes. The Fritz Speed package brings these two together to enable monitoring and graphing the WAN traffic of the Fritz!Box.

Dancing the DHCP Samba

After a hardware failure of a Linux computer I took the chance to set up a Debian installation from scratch. So I saved the data that was important to a server, burned the Debian DVD and installed it on the computer. When it came to networking it got a little more complicated: as the server […]
